One example, from www.jewfaq.org, is below.
Really, look into any Jewish source you like, and you will find Gehenna, the Jewish Purgatory. This is not deeply esoteric or secret knowledge.
Can I cite you a council of the Church that said this?
Of course not.
The Church hasn't paid attention to Jews on matters of theology since, oh, about the First Century.
Which is a pity, because some of the things that Jesus said become a whole lot clearer when seen through Jewish eyes.
From www.jewfaq.org:
Gan Eden and Gehinnom
The place of spiritual reward for the righteous is often referred to in Hebrew as Gan Eden (GAHN ehy-DEHN) (the Garden of Eden). This is not the same place where Adam and Eve were; it is a place of spiritual perfection. Specific descriptions of it vary widely from one source to another. One source says that the peace that one feels when one experiences Shabbat properly is merely one-sixtieth of the pleasure of the afterlife. Other sources compare the bliss of the afterlife to the joy of sex or the warmth of a sunny day. Ultimately, though, the living can no more understand the nature of this place than the blind can understand color.
Only the very righteous go directly to Gan Eden. The average person descends to a place of punishment and/or purification, generally referred to as Gehinnom (guh-hee-NOHM) (in Yiddish, Gehenna), but sometimes as She'ol or by other names. According to one mystical view, every sin we commit creates an angel of destruction (a demon), and after we die we are punished by the very demons that we created. Some views see Gehinnom as one of severe punishment, a bit like the Christian Hell of fire and brimstone. Other sources merely see it as a time when we can see the actions of our lives objectively, see the harm that we have done and the opportunities we missed, and experience remorse for our actions. The period of time in Gehinnom does not exceed 12 months, and then ascends to take his place on Olam Ha-Ba.
Only the utterly wicked do not ascend at the end of this period; their souls are punished for the entire 12 months. Sources differ on what happens at the end of those 12 months: some say that the wicked soul is utterly destroyed and ceases to exist while others say that the soul continues to exist in a state of consciousness of remorse.
This 12-month limit is repeated in many places in the Talmud, and it is connected to the mourning cycles and the recitation of Kaddish. See Life, Death and Mourning.
*Thanks for, finally, admitting that. You also can't cite anything from any authoritative Catholic Source to prove you are correct.
Will that stop you? No. You know better than the Church.
